NCS6433/D
NCS6433
Wideband Quad 2:1 Video
Switch
The NCS6433 is a wide bandwidth, bidirectional, Quad 2:1,
NMOS−based video switch suitable for dealing with video signals
such as RGB, composite, S−Video, and component video (YPbPr).
The NCS6433 is controlled by a single switch−enabled (OE
) input.
When OE
is low the switch is enabled and the A port is connected to
the B port. When OE
is high the switch is disabled and the
high−impedance state exists between the A and B ports. The line select
(SEL) input controls the data path of the multiplexer/demultiplexer.
The NCS6433 has a wide bandwidth, low crosstalk, low on
resistance, and fast switching times making it suitable for
high−frequency video applications in high definition LCD TV’s.
